    摘要： Disclosed is a process for forming a novel ink jet printhead which comprises: (a) providing a lower substrate in which one surface thereof has an array of drop generating elements and addressing electrodes formed thereon; (b) depositing onto the release surface of an intermediate film support a photopatternable layer comprising a precursor polymer which is a phenolic novolac resin having glycidyl ether functional groups; (c) prebaking the photopatternable layer to dry, semi-solid condition; (d) laminating the dry, semi-solid layer to the surface of the lower substrate under heat and pressure and separating it from the release surface of the intermediate film support; (e) exposing the photopatternable layer to actinic radiation in an imagewise pattern corresponding to ink nozzles and developing to form a nozzle plate section, and (f) removing the precursor polymer from the unexposed areas, thereby forming ink nozzle recesses which are aligned to communicate with the drop generating elements and terminal ends of the electrodes of the lower substrate laminated thereto. Step (e) may be carried out either before or after step (d).

    摘要： Disclosed is a process for forming a channel wafer for a novel ink jet printhead, having an ink particle-filter layer over the ink-inlet surface thereof. The process comprises the steps of applying a thin coating of a heat-curable, photopatternable polymer composition to an intermediate substrate having a release surface and drying the coating to form a semi-solid adhesive layer. The layer and supporting substrate are pressed against the ink-inlet surface of a channel wafer with an optional adhesive layer to bond the layer to the ink inlet surface. The substrate is separated to transfer the contacting area of the semi-solid layer to the ink-inlet surface as a laminate, and the semi-solid layer is exposed through a filter-forming mask and ink particle-filter openings are developed therethrough, either before or after transfer of the semi-solid adhesive layer from the intermediate substrate to the ink-inlet surface of the channel wafer, and the filter layer is cured.
